Y + R + V = 42
but 4 YEARS AGO : (R-4) +(V-4) = Y
Replace Y in the 1st equation by: (R-4) +(V-4)
(R-4) +(V-4) + R + V = 42
2R - 2V - 8 = 42; 2R -2V = 50, or R+V=25
IF R+V =25 AND Y + R +V = 42, then Y + 25 = 42 and Y =17

Answer:
6
Step-by-step explanation:
a1(n-1) + D
d = 6
I'm not good at math but it could be 17. NOT for sure, but I hope I helped! ( :
